Event Data Recording
Other modules in your vehicle — event data recorders — are capable of
collecting and storing data during a crash or near crash event. The
recorded information may assist in the investigation of such an event.
The modules may record information about both the vehicle and the
occupants, potentially including information such as:
•how various systems in your vehicle were operating;
•whether or not the driver and passenger seatbelts were buckled;
•how far (if at all) the driver was depressing the accelerator and/or the
brake pedal;
•how fast the vehicle was traveling; and
•where the driver was positioning the steering wheel.
To access this information, special equipment must be directly connected
to the recording modules. Ford Motor Company and Ford of Canada do
not access event data recorder information without obtaining consent,
unless pursuant to court order or where required by law enforcement,
other government authorities or other third parties acting with lawful
authority. Other parties may seek to access the information
independently of Ford Motor Company and Ford of Canada. Please note
that once 911 Assist (if equipped) is enabled (set ON), 911 Assist may,
through any paired and connected cell phone, disclose to emergency
services that the vehicle has been in a crash involving the deployment of
an airbag or, in certain vehicles, the activation of the fuel pump shut-off.
Certain versions or updates to 911 Assist may also be capable of
electronically or verbally disclosing to 911 operators the vehicle location,
and/or other details about the vehicle or crash to assist 911 operators to
provide the most appropriate emergency services. If you do not want to
disclose this information, do not activate the feature. See yourSYNC
supplement for more information.
Notice to owners of pickup trucks and utility type vehicles
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
Before you drive your vehicle, please read thisOwner’s Guidecarefully.
Your vehicle is not a passenger car. As with other vehicles of this type,
failure to operate this vehicle correctly may result in loss of vehicle
control, vehicle rollover, personal injury or death.

Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/gallon or liters/km.
If you calculate your average fuel
economy by dividing miles traveled
by gallons of fuel used (liters of fuel
used by 100 kilometers traveled),
your figure may be different than
displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET control (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
Instantaneous fuel economy
Select this function from the INFO
menu to display your instantaneous
fuel economy. This will display your
fuel economy as a bar graph ranging
from
poor fuel economy to
excellent fuel economy. As the bars
increase from left to right, the
instantaneous fuel economy is
increasing.
Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows one or no bars
illuminated. Instantaneous fuel economy cannot be reset.

FUEL PUMP SHUT-OFF SWITCHFUEL
RESET
The fuel pump shut-off switch is a device intended to stop the electric
fuel pump when your vehicle has been involved in a substantial jolt.
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated.
The fuel pump shut-off switch is
located in the passenger’s foot well,
by the kick panel.
Use the following procedure to reset the fuel pump shut-off switch.
1. Turn the ignition to the off position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in on the reset button.
4. Turn the ignition to the on position. Pause for a few seconds and
return the key to the off position.
5. Make a further check for leaks in the fuel system.
